Hi, The TwinRx frequency specifications is from 10MHz to 6GHz.
However, some tests shows that I can select the center frequency around 10 MHz with a sampling frequency of 25MHz which allows to make some acquisitions in the HF band (3-30 MHz) with a very good quality. My question is: why the specs limits to 10 MHz ? Is the RF part have degraded performances under this frequency ? Below this question is: we have to deliver a big HF (3-30 MHz) system to a customer. The acquisition part is actually built with 2 x N210 with LFRX daughter boards. Due to the lack of chain gain of this configuration, we add some RF pre-amplifiers in order to have good RF levels at the LFRX input. Maybe that this configuration can be replaced by 1x X300 + TwinRx (we didn't make this choice because of the TwinRx specs) ?
